AUTOMATIC CONTRIVANCE FOR RECEIVING VVEETTEN MESSAGES BY TELEPHONE- AppIioation filed December 6', 1928, Serial No. 324,210, and. in Austria April 21, 1928.-

This invention relates to an apparatus for receiving in written form messagestransmit tedover telephone circuits; so that, when a party is called and is found to be absent, the

caller is enabled, by manipulating the appa ratus in a predetermined manner, to cause what he has to say tobe written down at the other end of the circuit, for the party called to read upon his return. a

An object of the invention is to provide an apparatus of such design that the message sent can be imprinted upon a strip of paper, by means of types which are brought successively into proper position to spell the words of which the message is composed. The types are mounted upon a single movable member, which can be soactuated in accord ance with impulses of electric current pass ing through the circuits, that the typepre? senting the desired letter, figure or other'symbol can always be carried into operative po sit-ion with respect to the paper, and an im print of the letter or the like; then produced. In my copending application, Serial No. 320,026 filed the 17th day of November, 1928', for patent on automatic contrivance for re ceiving written messages'bytelephone, I. have shown and described an arrangement of circuits together with certain parts forproduo. 3!) ingthe same effects. This application covers particularly the essential mechanical con struction of the parts of the contrivance which themessage is tahen down, and the manner in which they are mounted. so as '35 to be movable as required; and to that extent is supplemental to my copending application afor'esaid. v

In practice the: apparatus is adapted to: be utilized in. connection with. telephone 40 cuits in Which the connection with a calledl subscriber is given by means of a dial bearing letters and figures; so that'theci'rcuit of the subscriber to be called can be connected by working the dial to give the number and, if necessary, the local exchange as. well. The apparatus, however, can also be used where. the telephone equipment isfln'ot of the automatic type, but in such cases the callers telephone must. be furnished with a. dial if hedesires to be able to send messages and have them written down "for the benefit of the party he is calling.

A further object of the invention is to provide a contrivance of this nature so designed that its principal parts are actuated released by electromagnets through which impulses of, electric current are passed the apparatus including not only a member carrying the types and the necessary elements for causing the types to be brought into po sition,but also suitable parts for causing a strip or length of paper to be fed at the requlred speed past the member carrying the types, together with an inking element or typing ribbon which is likewise automati- Cally moved combination with the paper ;1 and a type-bar or lever which strikes the Paper and the typing ribbon against the types soas to cause the outline of the types to be imparted to and retained: by the paper.

Another object of the invention is to provide an automatic contrivancefor receiving written messages by telephone which is certainqand' effective in operation, made up of relatively few parts and very compact in its design and arrangement so that it can easily be installed in connection with any telephone apparatus now in use: i

The nature of the invention audits further objects and advantages are set forth in the following description, taken with the accompanying drawings by which a preferred form of the invention is illustrated. The dis closure, however, is explanatory only and details ofshape, size and arrangel'nent of various parts may be varied without exceeding the scope and meaning of the terms of the appended claims.

On the drawings, Figure' 1 is afront elevation of an automatic contrivan'ce for receiving written mes- Figure 2' is a side elevation thereof; Figure 3 is a top plan of certainof the parts for producing. the feed of the inking ribbon andthe paper upon which the message is recorded; j Figure 4; is aside view of said parts; and Figure 5 shows a detail.

sages by telephone according to my inven- On the drawings the same numerals identify the same parts throughout.

In the particular description of the draw ings, the numeral 1 indicates a drum or typecarrying member which is generally cylindrical in shape and bears a number of characters 2 in arc-shaped rows on its outer surface. WVith an axis of the member 1 vertical, as shown in Figure 2, the rows of type are horizontal and extend a given distance around the circumference of the member 1; and these characters may consist of letters, figures or other symbols. Member 1 is aiiixed to a spindle 3 and is held fast between collars 4 made fast on the spindle so that the member 1 is rigid with the spindle; but the spindle 3 and member 1 can rise and fall or be rotated together about the longitudinal axis of the spindle 3.

Thus to bring into position a particular one of the types to be printed on the paper, the spindle 3 and carrier 1 are first lifted to bring the horizontal row of types containing that particular character up to the required level; then the spindle and type-carrying member are turned to cause the particular type desired to be brought opposite the paper against which it is to be pressed. The inven tion contemplates the use of a so-called Strowger switch, well known in'connection with automatic telephone circuits, to control the impulses of current which are sent through the circuits; and these impulses actuate a magnet to lift the member 1, a magnet to turn the member 1, and a third magnet to release'the member and let it return to its original position. -The Strowger switch, as set forth in my aforesaid copending application, is modified somewhat; having no contact track and no contact forks; and the recording of the message is effected entirely by the member 1 with the types 2through ac tuation of this member in the desired manner.

The working parts of the contrivance are mounted upon a support comprising uprights 5, connected by a transverse bar 6, upon which is mounted a frame 7 between the uprights 5. At the outer end of the frame, spaced from the uprights 5, is a bracket 8 the lower end of this bracket being bent outward as shown at 9; and the lower half of the bracket being provided with a central vertical slot 10 which opens through the lower out-turned end 9 to make room for the spindle 3. To the lower face of the end 9 and bridging the slot 10 is affixed a member 11 having an opening to serve as a bearing in which the spindle 3 can turn and move up and down. The top of the bracket 8 is turned outward as shownat 12 and this top is centrally recessed to receive the spindle 3, but carries on its upper face a piece 13 bridging this recess, similar to' the piece 11 and perforated to serve as another bearing for the spindle 3. All the parts. thus far described may be of metal.

The magnet for raising of the spindle 3 and the type-bearing member 1, is shown at 14; the magnet for turning these parts is shown at 15 and the release magnet is shown at 16; all three of the magnets being mounted upon the frame 7 To carry these magnets I affix to the bracket 8 between the same and the uprights 5 a plate of metal 17 bent into the form of a U, the base of the U being directly secured to the rear of the bracket 8 and the arms of the U extending towards the standards 5. The magnet 14 is mounted by means of a part 18 secured to the upper arm of the U-shaped plate 17 by means of a screw or the like 19; this magnet, like the others, being an electromagnet with its axis in vertical position. Below it is the pivoted armature 20 supported above the lower horizontal arm of the plate 17. This armature projects forward and the spindle 3 carries a rack 21 made up of annular projections separated by grooves extending all around the spindle. This rack is normally disposed between the bearings 11 and13. To enable the, armature 20 to lift the spindle 3 and member 1, it is provided at its outer end with a pivoted pawl 22, the upper end of which engages the rack 21. and the lower end of which is connected to a spring 23 affixed to the armature 20. This pawl 22 may be mounted upon the armature 20 in any suitable manner and it will be located in the vertical slot 10 of the bracket 8. The lower arm and the vertical portion of the bent plate 17 may be slotted as shown at 24 adjacent the slot 10, so that the armature'2O can move up and down; and the bracket 8 will have a projection 25 which extends into the path of the pawl 22 so that, as the armature lifts, the pawl will be deflected outward to engage the rack 21; and when the armature drops, it can slide along the teeth of the ratchet 21 without lowering the spindle'3. To thisend the lowerface of the circumferential teeth of the rack 21 vare perpendicular to the axis of thespindle 3, while the oppo site faces fareinclined or rounded. A stop or projection 26 on the top of the bearing piece 11 in the slot 10 serves as a rest for the armature 20 and pawl 22 in their lower most position. The armature isprovided at its end remote from the pawl 22 with downturned ears 27 perforated to receive pivot screws 28 which engage projections 29 on the horizontal part of the plate 17 and thus, while the armatureis securely mounted, it can nevertheless move up and down about the pivot-screws as an axis. A springis providedto act upon the armature 20 to resist the pull of the magnet 18; this spring being shown at 30. It has the form of ahelical spring extending transversely of the frame 7 beneath the pivoted end of the magnet 20. One end of this spring-is attached'to the p je io 2% at. he: ight in Figure 21; i p-roj ection extending down-Ward p tS zitl e-piwt so -that the spring SO-Iiesbeneath the-pivot but parallel with a linejoiningthem-i, The other endof; the spring passes; through an opening inthepart 29-ofthe plate 17 and is there affixed to a. fiat head; 31 which. can be held, in notches 32 By pulling. this head out and; turning it the t'orsion of the spring is varied. Normally the; spring tends to hold the armature 20 down and pulls it down whenever-the; magnet 114: isdead.

Theend of the upper arm ofthe U-shaped plate; 17 is turned down. as indicated and fastened; to insulation 34- carrying several; electrical contacts 35 which may engage contacts 86 of, insulation at the top of the standard 5'. These contacts enable connections to be conveniently made for energizing the magnet-14L, and the magnets. 15-. and 16, as; well As shown in; Figure 1:, the vertical rack bar 21; on; the: spindle 3 has a vertical slot there-in; indicated at 3-8 and. attached to the front of" the bracket 8-, a projection; 39" has itsextremity projecting, into this slot. The slot; aliordsclearance to the end of the proj ection39, so that the spindle?) may rise; but after the spindle isturned, the; end: of the v projection. catches underneath one of? the teethio-f the rack21 and then: thespindlecannot move downward, until it is turned back to bring thev slot 38 and: the: projection, 3'9 again; into registry. I also mount upon the apparatus for the rack 21 amovable catch 40, which is carried; by; the armature ot the release magnet 16.,

The turning. magnet 115 may comprise two cured one end-of a torsion spring-46, the other end offthise springbeing, attached to thehead? Ha-which; fits into: a counterbored recess in;

the upper end of the plate 17' having notches;

so that thet'ensioin of the: spring 46'can be" adjusted inthe same manner asa'lready described in connection with the spring- 30. spring normally tendsto make the armature 43 resist the pull of the magnet 1?5.- The upper end of the armature has alateralrextension; 47; which projects towards thespindl'e 3' and carriesa pivoted pawlz8i This pawlis shown in top view in; Figure 5" and has the form.- of: a bell-crank lever, one end; of

This.

which strikesa guide 49-, on; its working; strokeand the other end of which, strikes a stop 501 on the top of the upper end 12 of the bracket 8,v on the return stroke of; the pawl. The pawL 48 is maintained under tension bymeans of the spring 230 shown in Fig. 5". This pawle turns the; spindle 8, by engagingpthe ratchet 51 which is made fast on this spindle above the bearing plate 135' Hence every time the armature i3 is attracted the ratchet 51 is: turned throughthe space of one tooth which corresponds: to the distanceapart of thetypes of any one of the arc sh-aped rows on; the member 1'. Further in the upperend 123 of? the bracket 8 at the side opposite the bloclr 50 isa stud 5-2 which passes through an openingin a plate 53, the opposite endof; which is perforated to; give: passage tothe upper endgof the spindle 3. This plate 53 has a downturn-ed projection 54v and the: ratchet Wheel 51 has a stop 55, which strikes this. projection 5a and; thus limits the turning movement of the ratchet wheel 51, the spindle 3', and the type-bearing member 1 At 56 is; ahollow' cap receiving the upper end of the spindle 3 which projects through the plate 53 and this cap may be rigidly attached: to the plate 53: so that it does not move; while the: end of the spindle can turnin this cap 56. This. cap may contain a spring made fast at one end to the inside of the cap and toy the spindle 3 at the other the spring in; question being indicated at 57. in dotted lines. This spring is a torsion spring and: normally tends to turn the spindle 3 and member 1 baclc to starting position but is overcomewhen the magnet 15 acts to turn: the spindle 3anddrum 1.

The magnet 16 which is the magnet for releasing the spindle: 3 and member 1 is shown mountedv on the top of the upper part of the plate 17, being fixed to a mounting piece 58: made fast'to a: projection 59 extending upward from one end oii the upper part of the plate 17 To secure the magnet and: projection 59" together 15 may use screws the same as the screws which secure the magnets l and; 15". The armature for the mag.- net 126i is: shown at; 60 and it. is pivoted by means, of screws-441amounted: the upper and; lower parts of the plate 17 the same as thescrews 4a in the armature 4:3. The armature 60 is, thus in vertical. position turning about a vertical" axis. passing throughthe piVot screws 4:4. It carries a! fixed: projection 61- which acts as a stop for the ratchet:

51' and carries at its lower end; the fixed catch 40. To the armature is connected a. spring 62'; the other-end of which is joined toa pi-n\63 l'ield fast in a perforatedprojection 6% by means of a screw or other element so that the tension of the: spring: 62- can be adjusted; The spring normally pulls the armature soas to turn, it about itsvertical axisv and; move 1 the catches 40 and 61: into; en.-

gagement with the rack bar 22 and ratchet 51. heinhowever, the magnet 16 is engaged it pulls the armature 60 in the opposite direction, turning the armature about the pivot-screws IA-a againstthe force of the spring 62 to withdraw the catches 10 and 61. As indicated in Figure 1, the magnet 16 is located to the rear of the pivoted middle of the armature 60, while the catches 10 and 61 are attached to a part of the armature which extends forward from the pivot-screws. Hence the pulling of the armature by the magnet withdraws the stops 10 and 61 and the interruption of the circuit through the magnetpermits the spring 62 to pull the stops 19 and 61 into operative position.

- Thus in practice when a message is to be written down impulses of current are first sent through the lifting magnet 1a which acts upon the armature 20 to lift the spindle 3 and typebearing member 1 so as to bring into operative position the row 'of types which carry the letter or other symbol desired. The catch 40 engages the rack bar 22, spring 62 yielding, and permits the spindle 8 to rise step by step without allowing it to drop with the drum 1 downward. When the row of types containing the desired charac-v ter has been lifted into poistion, the magnet 15 is energized by successive impulses to operate the armature l3 and through the pawl 48 to engage the ratchet 51 and turn the spindle 3 and the type-bearing member 1 until the required character comes opposite the paper. As soon as the turning of the spindle 3 begins, the fixed catch 39 no longer registers with the slot but projects between the adjacent teeth of the bar of the rack 21. The strip of paper is shown at 65 and the inking ribbon is indicated at 66. Both pass together over the type-carrying member 1 and between the same and a printing bar or lever 67 which is actuated by a magnet presently to be described to strike against the paper 65 and ink ribbon 66 and force them against the member 1. The ribbon 66 moves between the member 1 and paper, 65 and when the printing lever 67 is thrown against the paper 65 it presses the paper and inking ribbon together against the type to be imprinted upon the paper. .Then the release magnet 16 can be energized to attract the armature to withdraw both catches 40 and 61. The spring 57 now turns the spindle 3 and member 1 until the vertical slot 38 in the rack 21 comes adjacent the fixed stop 39 and then the'member 1 and spindle 3 can fall down to their former position.

The bar 67 is shown as mounted on a pivot 68 between two parallel supports 69 affixed to ail-upright 70. This upright also carries a. magnet71 below the parts 69, and when this magnet is energized it willattract the bar 67 with sufficient force to cause the upper end of it to strike against the paper and typing ribbon 66. The paper comes from a reel 72 mounted upon a pivot 73 carried by a support 7 4. The outer end of the frame 7 has downwardly-extending vertical bearings 75 at the two sides thereof beneath the end 9 of the bracket 8; and in these bearings are mounted round verticalbars 76 being secured in any suitable manner to the bearings 75 and end 9 of the bracket 8. Thesevertical bars 76 serve as supports for the members carrying the spools for the typing ribbon 66 which may be prepared like anordinary typewriter ribbon. To one'of these verticalbars 76 shown at the left in Figure 2, in affixed a lateral arm 77 by' means of a clamp 78 and this arm 77 supports a bar or frame 79 having a guide 80 over which the paper 65 passes as it comes from the reel 72. This guide 80 may have the form of a suitable horizontal flanged roller mounted in bearings, with the paper 65 movable in contact with this roller and on to a second guide comprising a vertical flanged roller 81 in a suitable frame or bearing 82. From this flanged roller the paper strip 65 runs into a guide sleeve 83 and is drawn forwardby the action of a magnet 84L, which turns a feed roll 85 cooperating with another'flange'd guide roll 86, so arranged that the paper passes between the feed 85 and guide roll 86, as shown in Figure 2 at the right. This magnet 84 together with the rolls 85 and 86 are sustained from the other ly attached a pawl in the form of a flexible leaf-spring 9 1 having its end bent over to engage the teeth of a ratchet wheel 95; so that when the magnet -8 1is actuated, the

armature 90 is drawn toward the magnet 84 in such a way that the lateral arm 93 with pawl 94move to the right in Figure 2. To support the ratchet 95 I'aflix a horizontal U-shaped frame 96 to "the side of the frame or plate 89 supporting the magnet '84:; and the ends of the arm'of this frame 96 are perforated to receive the shaft or spindle 97 of the ratchet 95. Furtherattached to the bottom of'the frame 96 is an arm 98 to which 7 is pivoted the arm 99 which carriesthe guide roller 86. A spring 100engages the outer end of the arm'98 and the outer end of the arm 99 in such away as to force this arm with the roller 86 towards the roller 85:, so

I I I I I The two spools of the typingribb'on 66 are shown at 104:; the ribbon being unwound from thespool at the left andt'akenup'upon the other spool. The spool uponwhioh the ribbon is unwound is supported np'on a journal 105 capped by a retaining nut106; thisournalbeing aflixed to one end of arm (7. The other spool upon whichfthe riloboniis taken up is mounted upon a journal 107, which carries afixedratchet wheel 1'08; to be engaged and turned bythe armature 'of a magnet in the same manner as the ratchet95 of the roller 85 is rotated, This magnetis shown at 109 affixed to a support 110in th-e form ofaplate carried bythe'bar '88. The magnet 109 has an armature 111 pivotally mounted upon the plate 110 by means of screws 112. As shown in Figure t,"the p"lat e 110 extends rearward dfthe adj aceiit vertical bar 76towards the uprights 5; and the pivot screws "112 of'the armature '111 fareat the end of the magnet adjacent the standards '5. The

armature hasan extension 118, runningforward beneath the magnet 109 andhaving .on its end a lateral arm 930; with leaf-spring pawl 9l'asimilar to the arm 93 and pawl 94 above described in'connection with the armature 90. This extension 113 and pawl 94a s'erveto engage the ratchet 108, so thatevery time the magnet 109 'is'energizedthe ratchet 108 is rotated throughthe space of one tooth. The plate 110 carrying the magnet 109 may ,l have alfined thereto a *U-shaped horizontallydisposed frame 96a similar to the frame above-mentioned, with the outer ends of its arms perforated for the spindle 107. The

ratchet 108 will be below the rm orma na a. 6 and the spool for taking upthe type ribbon '50 above it. The lower arm of the frame 96a may also carry a pawl 101a to prevent back ward movement of the ratchet 108. I

Beneath the arm 77 is 'a support 115 carrying a number of leaf-spring contacts 116,and

the lower end of the lever 67 for striking the paper may have an insulating knob 117 thereon to press upon these contacts "and'co'ntrol certain circuits when the magnet. 71 at- I The vertical bar 76 which carries the clamp 7 8 has attached thereto another clamp 118 above thecla'mp78, carrying plates of insulation and ."several spring contacts 119. These contacts may be controlled so that the endof one of them may be bent to enter a vertical groove 120 in the inembe I 1 "so when this ,Ineniber turns into preper position theentrance intothis groove of said cont'act will separate the'two contacts at thispoin-t.
